Hi,
Welcome to ehealthforum.
CMV infection in newborns or congenital infection affects mortality rates. If the child survives the infection, then long term sequelae of neurological and neurodevelopmental effects follow. The child may have to cope with growth retardation, mental retardation, hearing loss, retinitis, atherosclerosis, increased risk for malignancy etc.
The calcifications detected in brain could suggest future development of cognitive and audiologic deficits along with poor neurodevelopmental prognosis.
